  1. Trigger/Timing Logic Unit (TLU) for AIDA Beam-Test David Cussans, AIDA Kick-Off, February 2011

  2. Outline David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Exiting EUDET JRA1 TLU • Aims for Mini-AIDA-TLU (mTLU) • Specification • Schedule • Cost • Aims for AIDA-TLU (aTLU) • Use of aTLU as Beam-Interface (BIF) • Summary

  3. EUDET JRA1 TLU David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Designed to give a simple but flexible interface to trigger/timing signals at EUDET JRA1 beam-telescope • Produces triggers from beam scintillators. • EUDET-Memo-2009-4

  4. JRA1 TLU Interface David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Different triggering modes: • No handshake (trigger pulses high) • Trigger-Busy handshake • Trigger Data handshake

  5. JRA1 TLU Interface David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Triggers can be vetoed by DUT raising TRIGGER_CLOCK line. • Can be combined with simple trigger/busy handshake for “dead-time free” readouts that send a continuous stream of data. • Send “buffer almost full” signal. • Time-stamp stored for each trigger.

  6. AIDA TLU David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Existing EUDET will continue to work and have compatible DUT interface. • Need a new TLU • Increased trigger rate: Move to one-trigger-per-particle for LHC detectors. • FPGA system available for lifetime of AIDA • Cheaper to produce TLUs for integration in home labs.

  7. AIDA Mini-TLU (mTLU) David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Want to produce a prototype to test out ideas • This mini-TLU will be cheaper and easier to produce than existing TLU • Use new connector standard (FMC), increase lifetime. • Enthusiastically adopted by CERN: 11 FMC projects already

  8. AIDA mTLU specification David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Double-Width FMC with single LPC connector. • Use e.g. Xilinx SP601 to host. 75mm 139mm

  9. AIDA mTLU Front Panel David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Four PMT inputs (Lemo-00) • One clock I/O (2-pole Lemo-00) • One GPIO (Lemo-00) • Two DUT (HDMI)

  10. AIDA mTLU Interface David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Four PMT Inputs (Lemo-00) • Use ADCMP551 fast comparator. <1ns propagation, ~ 100ps dispersion with amplitude. Threshold by DAC. +/-5V range. • Two DUT interfaces (HDMI) • Wanted to use RJ45 (compatibility), but won't fit on FMC • “Dongles” for conversion to LVDS/RJ45 or TTL/LEMO

  11. AIDA mTLU Interface David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Use clock circuitry inside FPGA to receive or generate clocks. • Communication to DAQ by Gigabit Ethernet • Use “IPBus” firmware developed for LHC. • Will need a host to convert packets into EUDAQ format, but could be main DAQ PC

  12. Versions of mTLU David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Different levels of build • Assembled into box ( “beam-test ready”) • Assembled onto metal plate ( “IKEA”) • Approximate cost ~ €1000 each. • FMC only - provide own FPGA ( “Aldi” ) • Manufacture own from design files • Aiming for hardware ~ April 2011

  13. Beam Interface Prototype David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Requirement for CALICE beam-interface (BIF) for beam-test. • Can use mTLU as prototype BIF • HDMI connector physically compatible with DIF-LDA link. • Full aTLU as a BIF • Hardware should work – but BIF-specific firmware needed.

  14. Full AIDA TLU David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Approximate specification: • Twelve PMT inputs • Six DUT inputs • Low jitter clock generation • Will need FPGA board with FMC-HPC (high pin count) connector. • Firmware almost identical to mTLU.

  15. Summary David Cussans, AIDA Kick-Off, 16-19 Feb 2011 • Work under-way to produce a AIDA mini-TLU • Aiming for early release • Low(er) cost way of integrating to EUDAQ at home lab. • Fully specify aTLU in light of mTLU experience • Can use same hardware (and probably most of the firmware) as a Beam-Interface (BIF)
